The grounding in natural sciences which I obtained in the course of my medical studies, including preliminary examinations in botany, zoology, physics, and chemistry, was to become decisive in determining the trend of my literary work.
A probing analysis of the problems of evolution forms the basis of my prose.
Whenever one reads of the determination of the species, or opens a book on natural science and history, in whatever language, one inevitably comes across the name of Linne.
During half a century of literary work, I have endeavoured to introduce the philosophy of evolution into the sphere of literature, and to inspire my readers to think in evolutionary terms.
